Benchmark

A benchmark for evaluating AI/LLM agents at reverse-engineering encryption protocols used by Android mobile applications. Each task provides a decompiled Android app and captured network traffic; the goal is to identify the cipher, extract the key material, and produce a working encryption implementation that can decrypt the captured ciphertexts.

File formats

input/ciphertexts.json

Array of ciphertext samples captured from network traffic.

[
  {
    "file": "input/traces/com.example.app.pcapng",
    "packet_number": 463,
    "ciphertext": "b31e48f9a23dcf1d...",
    "encoding": "hex"
  }
]

Field	Description
file	Relative path to the source pcapng trace file
packet_number	Packet index within the trace file
ciphertext	Hex-encoded ciphertext bytes
encoding	Always "hex"

expected_output/audit.json

Structured description of the encryption protocol. Validated against common/audit_schema.json.

{
  "ciphers": [
    {
      "cipher": "DES",
      "mode": "ECB",
      "padding": "pkcs7"
    }
  ],
  "vulnerable": true,
  "key_exchange": "none",
  "key_hex": "577331566378376e",
  "iv_hex": null
}

expected_output/encrypt.py

Executable Python script implementing the cipher. Follows the interface defined in common/encrypt_template.py:

python encrypt.py <plaintext_hex> [--key-hex KEY] [--iv-hex IV]

Reads plaintext as hex on the command line, prints ciphertext as hex to stdout. Applies only the cipher layer -- no compression, base64, or transport encoding.

Expects Python >= 3.11. Install from common/pyproject.toml:

cd common && pip install .

expected_output/plaintexts.json

Same structure as ciphertexts.json with an added decrypted field containing the known plaintext as a hex string:

[
  {
    "file": "input/traces/com.example.app.pcapng",
    "packet_number": 463,
    "ciphertext": "b31e48f9a23dcf1d...",
    "encoding": "hex",
    "decrypted": "7b22617070766572..."
  }
